Certified compliance & reliable quality: All hardware is engineered and tested to EN standards, with CE certification and test verification. This ensures our products meet building code requirements across markets, streamlining compliance review and project approval for end customers.
One-stop procurement: DIROCK supplies the full range of fire door hardware-from mortise locks and lever handles to profile cylinders, hinges —from a single source. Instead of coordinating multiple suppliers and managing incompatible certifications, you source a fully matched, ready-to-install system from a single manufacturer. This reduces procurement lead time, simplifies supply chain management, and cuts your coordination risk on multi-unit projects.
Proven fire safety performance: The hardware is tested as part of a complete door assembly to EN 1634-1 for fire resistance, and it maintains its function and contributes to the door's integrity and insulation rating during a fire event. By effectively containing flames and smoke, the system helps safeguard evacuation routes and supports firefighting efforts-meeting the stringent life-safety demands of hospitals, schools, commercial complexes, and public buildings.
Long-term durability & premium materials: Manufactured from high-grade stainless steel (SS304) and brass, the hardware undergoes rigorous durability testing to guarantee extended service life. The materials offer excellent resistance to wear, corrosion, and high-traffic fatigue, ensuring consistent performance and smooth operation over years of intensive use in public and commercial environments.
OEM & customization services: We provide comprehensive OEM support for door hardware brands, including custom surface finishes (satin, polished, PVD), private-label packaging, and logo engraving. Our technical team can also adjust configurations-such as the mortise lock function designs and dimensions -to align with your target market and brand positioning. Our ISO-certified factory, with scalable production capacity, supports your growth from trial orders to high-volume programs.
DIROCK's fire door hardware kits are engineered for high-traffic environments where compliance and life safety are paramount. Typical applications include:
Healthcare facilities: Hospitals, clinics, nursing homes, and rehabilitation centers.
Healthcare environments have high occupant density and demand exceptional cycle durability from door hardware. Reliable fire-rated hardware effectively contains flames and smoke spread. Corrosion-resistant, easy-clean stainless steel finishes meet the hygiene standards required in medical settings. Our EN compliant hardware supports building approval and compliance for healthcare projects.
Education & public buildings: Schools, universities, libraries, cultural centers, and community venues.
These venues experience heavy pedestrian traffic, extremely frequent door usage, and are subject to impact from human force and cleaning equipment. Fire door hardware must offer excellent impact resistance and resilience to rough handling, while meeting public building fire safety regulations.
Commercial complexes: Office buildings, shopping centers, hotels, and government administrative buildings.
Mixed-use buildings have diverse occupancy types and complex evacuation routes, placing high demands on hardware in terms of aesthetics, durability, and compliance. A fully matched fire door hardware kit simplifies on site installation and compliance verification, while adapting to the fire safety requirements of multi use buildings.
Transportation hubs: Airports, metro systems, and railway stations.
Transportation hubs experience heavy passenger traffic and continuous door operation, along with exposure to humid and corrosive conditions. 304 stainless steel fire hardware offers excellent wear and corrosion resistance; 316 material is available for high corrosion environments, ensuring long term reliable performance of fire doors.
